Letters Patent No. 90,854, dated June 1, 1869..

IMPROVED MOI 3E OI TREATING WOOD TO RESEMIBLE CARVED WORK.

The Schedule referred. to in these Letters Patent and making part of thesame.

To all 'whom it may concern Be it known that we, WILLIAM KOPP andWILLIAM WRAMPELMEIER, both of Louisville, in the county of J efi'erson,and State of Kentucky, have invented a new and useful Improvement inPressing Wood into Gertain Shapes to Rescmble Carved Work; and we dohereby declare the following to be a full and correct description of thesame, suflicient to enable others skilled in the art to which ourinvention appertains, to fully understand and use the same.

The nature of our invention consists in certain compositions, whichserve as glue, and as filling for the reverse side of the pressed wood,and in the method of applying these compositions when pressing wood intocertain shapessto resemble carvings.

Ve can, by our improvement, press carvings of any size and shape by onesingle operation, so that, when the pressed carving is taken from underthe press, it is complete, and ready to be used at once.

\Ve first take a sheet of good, common, strong paper,'such aswriting-paper, and spread on it a glue composed of five parts of cottagecheese, called, in the German language, schmierkacse, and as such knownin this country, and one part of lime, which we thoroughly mix. On thisglue we place another composition, consisting of six parts of sawdust,one part of the glue described, and one part of flour, well mixed. Ofthis second composition, we place sufficient on the glued paper to aboutfill the reverse side of the pressed wood. A little practice very soonenables the workman to determine the precise quantity, which, of course,varies with size of the carving to be pressed.

On this composition is then placed the piece of wood to be pressed. Thiswood ought not to' be thicker than one-eighth of an inch, or about thethickness of common veneering, though a small excess of that size doesnot make a material difierence; and we prepare it, to soften it, in anywell-known manner. The proper die, having cutting-edges, is then placedupon the wood, and the whole placed under a suitable press.

To prevent the edges of the die from being dulled by contact'with thecounter-plate or bed of the die, we place a piece of pasteboard on thesame, on which the paper bearing the composition, wood, and die, rests.

Both the counter-plate and the die are heated, so

that, when the pressure is exerted on the matter between them, and whilethe die is shaping and cutting the wood, to assume the shape of thecarving, their heat hardens the composition, which, by the pressure,fills the reverse side of the wood, and dries the glueof the paper,securing the latter to the carving, with which it is cut by the edges ofthe die, the glue, filling-composition, and carving, thus formiu g onehard lIlELSS.

Thus, by the one operation of pressing, which can be done'within oneminute, the carving is produced complete.

To prevent the diefrom sticking to the carving, we will oil the die,which, at the same time, gives a shining surface to the carving.

We have discovered that our glue and our fillingcomposition areinsoluble by either dampness or heat, when appiied as described, andthey are, consequently, especially adapted to the manufacture.

Having thus described our invention,

What we claim, and desire to secure Patent, is

1. The glue-composition, when consisting of the ingredients mentioned,and applied in the manner and for the purpose specified.

2. The filling-composition, when consisting of the ingredientsmentioned, and applied in the manner and for the purpose set forth.

3. The combination, in the method of pressing wood into shapes toresemble carvings, 850., of the glue and filling-compositions, whenapplied as and for the purpose described.
